Right now I use a receiver hooked up to my tv via toslink. I can only change te volume via the buttons on the reciever, because I lost the remote.
Changing te volume of the tv does nothing.
If I would hook up a nvidiashield would it also have this problem, or does it have it's own independent volume
Also heard there was a it blaster on the remote, but I can't seem to find a compatibility list too show me if my reciever would work with it.
My reciever is a pioneer sx sw series unit
Because I would love to have just one remote and not have to walk too my reciever to change volume
Yes... with a caveat. In your case, you could leave the receiver at close to max volume and then control the audio via the Shield's remote, unless the source material has multi-channel sound. Whenever Android TV plays something in Dolby Digital, for example, its volume control is disabled and it leaves volume control to the receiver.
I'd say just buy a new remote off ebay, or a universal one.
